Topics include:
•
screen functions
•
keyboard functions
•
backplane functions
•
clock functions
•
battery back-up

Library Overview This library lists programming macros, or macro CALLs that you can use while
programming with the BASIC development language. Included is a description of
what the macro CALL does, along with a list of inputs and outputs associated with
the macro.
Programming macros are described in Chapter 6 of this manual. The example
program in that chapter (SECOND.BDL) makes extensive use of these macros.
IMPORTANT
The file INCLUDE.BDL comes as part of the BASIC
Development software package. It contains all of the BASIC
programming macros listed in this library, along with the
information necessary to translate them. Review the contents of
the macro as listed in this file so you fully understand its
functions and interaction with its application. The statement
{$I
INCLUDE.BDL}
should appear at the beginning of any program in
which you intend to use these programming macros.
